Quick Start (EJB mode): Dynamically creating a DDX document using the Java API

The following Java code example dynamally creates a DDX document that disassembles a PDF document. A new PDF document is created for each level 1 bookmark in the input PDF document. This code example contains two user-defined methods:

  • createDDX: Creates an org.w3c.dom.Document object that represents the DDX document that is sent to the Assembler service. This user-defined method returns the org.w3c.dom.Document object.

  • convertDDX: Converts an org.w3c.dom.Document object to a com.adobe.idp.Document object. This method accepts an org.w3c.dom.Document object as an input parameter and returns a com.adobe.idp.Document object.

    Both of these methods are invoked in this quick start. (See Dynamically Creating DDX Documents.)

        * This Java Quick Start uses the EJB mode and contains the following JAR files 
        * in the class path: 
        * 1. adobe-assembler-client.jar 
        * 2. adobe-livecycle-client.jar 
        * 3. adobe-usermanager-client.jar 
        * 4. adobe-utilities.jar 
        * 5. jbossall-client.jar (use a different JAR file if the LiveCycle Server is not deployed 
        * on JBoss) 
        * 6. jacorb.jar (use a different JAR file if the LiveCycle Server is not deployed on JBoss) 
        * 7. jnp-client.jar (use a different JAR file if the LiveCycle Server is not deployed on JBoss) 
        *  The JBoss files must be kept in the jboss\client folder. You can copy the client folder to  
        *  your local development environment and then include the 3 JBoss JAR files in your class path 
        *  These JAR files are located in the following path: 
        * <install directory>/sdk/client-libs/common 
        * The adobe-utilities.jar file is located in the following path: 
        * <install directory>/sdk/client-libs/jboss 
        * The jbossall-client.jar file is located in the following path: 
        * <install directory>/jboss/client 
        * If you want to invoke a remote LiveCycle Server instance and there is a 
        * firewall between the client application and the server, then it is  
        * recommended that you use the SOAP mode. When using the SOAP mode,  
        * you have to include additional JAR files located in the following  
        * path 
        * <install directory>/sdk/client-libs/thirdparty 
        * For information about the SOAP  
        * mode and the additional JAR files that need to be included,  
        * see "Setting connection properties" in Programming  
        * with LiveCycle 
        * For complete details about the location of the LiveCycle JAR files,  
        * see "Including LiveCycle Java library files" in Programming  
        * with LiveCycle 
        * This quick start dynamically creates the following DDX document: 
        * <?xml version="1.0" encoding="UTF-8"?> 
        * <DDX xmlns="http://ns.adobe.com/DDX/1.0/"> 
        *  <PDFsFromBookmarks prefix="stmt"> 
        *    <PDF source="AssemblerResultPDF.pdf"/> 
        * </DDX>
